The display panel of the present disclosure comprises: a base substrate: a support layer, located on the base substrate, and comprising a plurality of support sub-layers stacked along a side facing away from the base substrate, wherein the support layer has cup-shaped structures passing through the plurality of support sub-layers along the thickness direction, a side wall of each cup-shaped structure comprises a plurality of sub-side walls sequentially connected in a direction away from the base substrate, and a corner structure is formed at a connecting portion of any two adjacent sub-side walls; and a plurality of light-emitting devices in one-to-one correspondence with the cup-shaped structures, wherein each light-emitting device comprises a first electrode, a light-emitting layer, and a second electrode sequentially arranged along a direction away from the base substrate, the first electrode at least covers the bottom of the corresponding cup-shaped structure, and at least a part of the first electrode further covers the side wall of the cup-shaped structure.
A display substrate and a preparation method therefor, and a display device. The display substrate comprises a hole area, a transition area surrounding the hole area, and a display area surrounding the transition area, wherein the transition area is provided with isolation columns surrounding the hole area, each isolation column comprising a first isolation portion and a first coating layer. The display substrate comprises a base. The first isolation portion comprises a second electrically conductive layer, and a first side and a second side of the first isolation portion respectively face the display area and the hole area. The first coating layer is arranged on the side of the first isolation portion away from the base, and coats one of the first side and the second side of the first isolation portion. The first coating layer is made of an insulating material.
